Santa Anna, Antonio López de ( born Feb. 21, 1794 , Jalapa, Mex.—died June 21, 1876 , Mexico City ) army officer and statesman who was the storm centre of Mexico’s politics during such events as the Texan Texas revolt (1836) and the Mexican-American War (1846–48).

The son of a minor colonial official, Santa Anna served in the Spanish army and rose to the rank of captain. He fought on both sides of nearly every issue of the day. In 1821 he supported Agustín de Iturbide and the war for Mexican independence, but in 1823 he helped overthrow Iturbide. In 1828 he backed Vicente Guerrero for president, only to help depose him later.

Santa Anna gained much prestige in 1829 when he fought against Spain’s attempt to reconquer Mexico, and he became known as the Hero of Tampico. This surge of glory helped him gain the presidency in 1833 as a Federalist and opponent of the Roman Catholic church; in actuality, however, he established a centralized state. He remained in power until 1836, when he marched into Texas to quell a rebellion by U.S. settlers there. During the course of this punitive expedition, Texas declared its independence from Mexico (March 2). Santa Anna, after defeating Texan forces at the Alamo (q.v.) and Goliad, then moved eastward to the San Jacinto River, where he was defeated and captured by Sam Houston on April 21. He was sent to Washington, D.C., for an interview with President Andrew Jackson, who returned him to Mexico, where he was forced into retirement.

In 1838, when the French navy seized Veracruz and demanded an indemnity for injuries to French citizens in Mexico, Santa Anna led forces to Veracruz, only to shoot at the ships as they departed. He lost a leg in the skirmish. He gained enough prestige from this event to act as dictator from March to July 1839, while the president was away. Two years later he led a revolt and seized power, which he held until he was driven into exile in 1845.

When war with the United States broke out, Santa Anna contacted U.S. president James Polk, who arranged for a ship to take him to Mexico for the purpose of working for peace. Santa Anna took charge of the Mexican forces upon his return; but instead of acting for peace, he led his men against the United States until he was routed by U.S. forces under General Winfield Scott. Santa Anna again retired, moving to Jamaica in 1847 and to New Granada in 1853. Ten years later he sought U.S. support in an attempt to oust the emperor Maximilian, whom the French had placed on the Mexican throne; at the same time, he offered his services to Maximilian. Both proposals were refused. Two years before he died, poor and blind, Santa Anna was allowed to return to his country.

Santa Anna possessed a magnetic personality and real qualities of leadership, but his lack of principles, his pride, and his love of military glory and extravagance, coupled with a disregard for and incompetence in civil affairs, led Mexico into a series of disasters and himself into ill repute and tragedy.
